Sakura Himedaka

Occupation: Guard of Spring

A young woman who cherishes Hinagiku greatly as her best friend and retainer. She falls into despair after Hinagiku's kidnapping and cuts ties with the Agent of Winter, Rosei, and his Guard, Itecho, soon afterwards, despite her lingering feelings for Itecho.

After Hinagiku's return, Sakura gradually lets the Winter duo back into her and Hinagiku's lives once the four reunite, internally accepting her feelings for Itecho and becoming closer to him in the process.
